Application filed March 2, 1887. Serial No. 229,409.

To @ZZ whom, it may concern.-

Be it known that I, ZEBULON Davis, of Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in vapor-stoves; and it consists in a vapor-burn ing apparatus comprising a generating-burner and side or supplemental burners supplied therefrom, and having between the generatingburner and the side burners lighting-tubes fed from the supply-pipes of the side burners, as will be hereinafter more fully set forth and claimed.

' The object of my invention is to provide a means for conducting lighted vapor or gas from one burner to the other, so that should the flame of one of the burners become accidentally extinguished from any cause it will be automatically relighted.

Figure 1 is a side elevation of a vapor-stove embodying my invention. Fig. 2 is an ernlarged detail view showing the construction of the connectingblock.

A represents the central burner and generator, and B the tubes or pipes through which the vapor is conducted to the end burners, C', in the usual manner. At any suitable distance between the two burners there is made a suitable opening, O, through the top of the tube, and which opening is covered over by means ofa Wire-gauze, D, through which the vapor can freely pass, but which will not allow the iiame to pass through. This wire-gauze is used as a means of safety, so as to prevent any possibility of iiame passing dowri into the pipe B from the one G. It so desired, it may be entirely dispensed with. Extending downward into the tube at any suitable angle, on the farther side of the opening C, from the direction in which the vapor passes to the burner, is a web, iange, or deflector, F, against which a portion of the passing vapor strikes for the purpose of being deflected upward through the opening C. Gast solidly upon the top of the in- (No model.)

ductiontube B are the two small tubes or pipes, G, which have their outer ends to approach sufticientl y near to to the burners A C to have the vapor escaping from their ends to ignite from the flames of the burners. The inner ends of these tubes or pipes G approach each other within asuitable distance upon each side of the opening C. In the top of the inductionpipe B, and driven tightly in between these inner ends,is the connecting-block I. Through this block are formed two longitudinal openings or passages, J Lwhich form continuous openings or connections between the pipes G and the burners. The smaller opening,L,con nects, by means of the transverse opening O through the bottom of the block, with the opening C through the top of the inductiontube, so that the vapor which escapes through the opening C will pass through the opening O into the passage Land escape in both directions into the pipes G. This passage L is made very small, so that the iiame will not pass through it, but will stop at each end thereof, while the passage J is made sufliciently large to allow the anie to pass freely through it and along through the tubes from one burner to the other.

When the end burner is in use and the induction-tube B is lled with vapor, a small portion of the Vapor is passing through the openings O O into the passage L in the block I, and is escaping from each end ot' the passage into each of the tubes B. This vapor tlows through the pipe G and burns intermittingly back and forth from one burner to the other. When the iiame in passing through the two pipes Gand block I reaches the end of the passage L, the flame stops at the ends without penetrating into the passage L, and then passes on through the larger passage, J,to either one of the burners. The passage L is made so minute that the flame cannot penetrate it, and hence the iiame does not burn over the gauze D, as it would if the passage were made large enough to admit of combustion within it.

The advantage of the construction here shown consists in forming a positive lightingtube which will light the burners, no matter how low their flames may be turned. There a tube simply extends from one burner to the other, the whole operation of automatically lighting consists in having one end of the tube catch sufficient gas to support a flame through the tube. Where the flames are turned down low, and but a very small amount of vapor is beingv used, the vapor does not escape with sufficient force to enter the tube and travel from one end of the tube to the other, and hence it fails to operate just when it is most desirable that it should; for it is evident that a burner which has its flame turned down low is much more liable to become accidentally extinguished by blowing out or otherwise than when it is turned on at a full size. It will be noticed that no vapor passes into the tubes B except when the end burners are in operation, and hence no waste of vapor takes place, as is the case where the ends of the pipes G are connected to the commingling-chambers of the burners between which it is placed.

Having thus described my invention, I claim 1. The combination of the generating and end burners, the induction-tubes which convey the vapor from the generator to the end burners, and lighting-tubes placed between the burners and communicating with the inductiontubes at any suitable points between their ends, and through which lighting-tubes the vapor burns back and forth between the central and end burners, substantially as shown.

2. The combination of the generating and end burners, the induction-tubes which convey vapor from the generator to the end burners, and which are provided with openings between their ends for the escape of a portion of the vapor that is passing through them, and the lightiugtubes located between the burners upon the induction-tubes and also provided with openings to receive the 'Vapor that escapes through the openings in the induction-tubes, substantially as described.

3. The combination of the center and end burners, the induction-tubes connecting the central with the end burners and provided with openings for the escape of a portion of the vapor passing through them, deflectors or webs extending downward from the openings, the lighting-tubes connected with the induction-tubes, the connecting-blocks placed over the openings in the induction-tubes and between the inner ends of the lighting-tubes and provided with two longitudinal passages of different diameters, and a transverse opening extending at an angle to the transverse passages, and the gauze which protects the openings' in the induction-tubes from the flame, substantially as set forth.

' In testimony whereof I affix my signature in presence of two witnesses.

ZEBULON DAVIS.
